SICK DFS60S-S4OA01024 Pro safety encoder with Sin/Cos incremental output, SIL2 and PL d rated for accurate speed and position monitoring.
The SICK DFS60S Pro safety encoder with Sin/Cos incremental output is designed for industrial machinery where precise motion feedback and certified functional safety are both mandatory. This encoder addresses the challenge of monitoring speed and position accurately while meeting modern safety standards such as SIL 2 and PL d. With high-resolution Sin/Cos signals and fine angular measurement, it enables reliable detection of movement even at low speeds. Its compact solid-shaft construction, wide operating voltage range, and robust housing make it suitable for integration into space-constrained machines operating in demanding industrial environments.
The SICK DFS60S Pro safety encoder provides smooth, high-fidelity Sin/Cos signals that support precise interpolation and stable control behavior in real-world applications. This results in accurate speed monitoring, controlled stopping distances, and predictable machine behavior during normal operation and safety events. Its safety-oriented design supports redundant evaluation concepts without increasing mechanical complexity. Built to withstand vibration, shock, and wide temperature variations, the encoder maintains consistent performance over long service life, helping machine builders reduce downtime, improve operational safety, and achieve compliance without sacrificing productivity.
The SICK DFS60S Pro Safety Encoder is chosen when motion precision and certified safety must coexist without compromise. It combines fine-resolution Sin/Cos feedback with safety-rated performance, enabling accurate speed and position monitoring even during slow or dynamic movements. Its robust mechanical design, wide operating temperature range, and long service life make it ideal for demanding industrial machinery. For machine builders, it simplifies compliance with functional safety standards while delivering the signal quality needed for smooth, stable control across the entire operating range.
The SICK DFS60S Pro Safety Encoder solves the challenge of reliably monitoring rotating motion in safety-critical applications where standard encoders are insufficient. In machines with high inertia, frequent starts and stops, or low-speed operation, inaccurate feedback can lead to unsafe stopping distances or nuisance shutdowns. This encoder provides precise, continuous motion information that safety controllers can trust, reducing false trips, improving stop accuracy, and ensuring consistent machine behavior under both normal operation and emergency conditions.

In automated conveyor systems used for packaging, sorting, and distribution, controlling speed accurately is essential to protect operators during access or maintenance. The SICK DFS60S Pro safety encoder is installed on the motor or gearbox shaft to deliver continuous Sin/Cos feedback with fine resolution. This allows safety controllers to evaluate speed reliably, even during slow jog movements or controlled stops. The high signal quality minimizes speed fluctuations and false alarms. As a result, conveyors achieve predictable stopping distances, smoother motion profiles, and improved uptime while meeting strict functional safety requirements.
Industrial robots operating in shared workspaces require dependable motion monitoring to prevent hazardous movements. The SICK DFS60S Pro safety encoder is used on rotary axes or auxiliary drives to provide accurate speed information for safety functions such as limited speed or controlled stop. Its small measuring step enables detection of very slow movements that standard encoders may miss. This improves safety response during teaching or manual guidance modes. The robust mechanical design withstands constant acceleration and vibration, ensuring stable feedback and consistent safety performance throughout long production cycles.
Web-processing machines for printing, laminating, or coating depend on precise speed synchronization to maintain material tension and product quality. The SICK DFS60S Pro safety encoder is mounted on drive rollers to supply smooth, continuous motion feedback to both control and safety systems. Its differential Sin/Cos signals remain stable in electrically noisy environments, reducing measurement errors. During setup or cleaning operations, the encoder enables reliable low-speed monitoring, protecting operators while preserving accurate speed control and minimizing waste caused by misalignment or uneven material feed.
In automated lifting systems, uncontrolled motion or delayed braking can create serious safety risks. The SICK DFS60S Pro safety encoder is applied to crane drives or hoist motors to monitor rotational speed under varying load conditions. Its ability to deliver precise feedback during acceleration, steady travel, and deceleration helps safety systems enforce controlled movement limits. Designed to tolerate shock, vibration, and wide temperature ranges, the encoder maintains consistent performance in harsh environments, improving stopping accuracy and enhancing overall operational safety for heavy-load handling applications.
